Lorex has received 488 reports of overheated and expanded batteries, and in 140 of those reports the battery pack's swelling caused plastic casing to open or come off. While the overheated batteries are a burn hazard, no injuries have been reported to Lorex.

The monitors — sold at online and at Babies "R" Us, B&H, Best Buy, Target, the Home Depot and Walmart — should no longer be used and Lorex is offering full refunds.
